10、 1 Supporting multiple air interfaces Summary Recommendation ITU-T H.621 defines the system architecture for the multimedia information access triggered by tag-based identification on the basis of Recommendation ITU-T F.771, and serves as a technical introduction to subsequent definition of detailed
11、 system components and protocols. The services treated by this Recommendation provide the users with a new method to refer to the multimedia content without typing its address on a keyboard or inputting the name of objects about which relevant information is to be retrieved. This is one of the major
12、 communication services using identification (ID) tags such as radio frequency identifications (RFIDs), smart cards and barcodes. International standardization of these services will give a big impact to international multimedia information services using ID tags. It contains the functional model, i
13、ts constituent components as well as its workflow. An appendix describes how this architecture realizes typical services. Amendment 1 (2014) clarifies that an ID terminal can have and supports multiple radio frequency (RF) communications. History Edition Recommendation Approval Study Group Unique ID

ITU-T H.621 (2008)/Amd.1 (10/2014) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication tech
16、nologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telec
17、ommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some ar
18、eas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized op
19、erating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “sh
20、all“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the pr
21、actice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation deve
22、lopment process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

32、Optically Readable Media P2P Peer to Peer 6 System functional architecture 6.1.2.1 ID tag R/W An ID tag R/W is required to provide communication interfaces to an ID tag, and read a single or multiple identifier(s) as well as application data from the ID tag. After reading the identifiers, it sends t
33、heir information to the MIDF. An ID terminal can optionally contain multiple ID tag R/Ws An ID terminal can optionally contain multiple ID tag R/Ws where a selection function of frequency bands is required to choose a proper ID tag R/W interface against multiple RF types of ID tags such as HF-type I
34、D tags and UHF-type ID tags. The selection function may be provided via a manual selection user interface, an automatic scanning function or other ways which are an implementation issue. Similarly, selection function of optically readable media (ORM) (1-dimentional, vs 2-dimentional, different type
35、of 2-dimentional codes, etc.) is an optional feature which can be provided via a manual selection user interface, an automatic scanning function or other manners which are an implementation issue. 6.1.2.2 Multimedia information discovery function (MIDF) Appendix II Workflow examples for multimedia i
36、nformation access triggered by tag-based identification (This appendix does not form an integral part of this Recommendation.) This appendix presents five seven typical examples of multimedia information access triggered by tag-based identification included in ITU-T F.771. For each example, its appl
37、ication scenario is described, and then the functional architecture and associated workflow are presented. Here, to make the description simple, the service broker is not used in the architecture and workflow. II.5.3 Workflow 1) ID tag R/W of the theatre seat obtains the visitor identifier from the
38、visitors ticket. 2) ID tag R/W sends the visitor identifier to the MIDF in the presence management application. Rec. ITU-T H.621 (2008)/Amd.1 (10/2014) 3 3) MIDF sends the visitor identifier to the IDR to find the theatre management servers associated with the visitor identifier. 4) IDR informs the
39、pointer and transfer protocol of the theatre management servers to the MIDF. 5) MIDF sends the information to the MIHF, which, in turn, requests the theatre management servers to obtain the presence information. 6) The server replies with the presence information. 7) Multimedia information browser u
40、pdates the presence information according to the received information, and shows it to the theatre manager. II.6 Food safety check and purchase II.6.1 Application scenario This application scenario is associated with the use case scenario of I.4, “Food traceability“, in Appendix I of ITU-T F.771. A
41、consumer wants to check with his/her smartphone the origin of production, the route of supply and the current status of quality for a food item before the purchase. The food item has been attached a UHF-type RFID tag. The smartphone has a dual-band RFID reader/writer to communicate with both HF and
42、UHF ID tags, where the HF communication feature of the dual band reader/writer is provided by the NFC technology. The user instructs the smartphone to do a food safety check and gets a response containing safety and other information from the food trace information server. If the user is satisfied w
43、ith the information, he/she proceeds to buy the food item. The user enables a payment feature of the smartphone and approaches the smartphone to a payment terminal with an HF-type (NFC-type) ID R/W, for the payment. A payment receipt is returned to the user after the payment succeeds. II.6.2 System
44、architecture In this scenario, the configuration of the system is illustrated with the following representation relationships: Smartphone: ID terminal UHF ID tag: UHF-type RFID tag working as an ID tag HF ID tag: HF-type RFID tag working as an ID tag by NFC ID tag R/W a): UHF-type RFID R/W ID tag R/
45、W b): HF-type RFID R/W 4 Rec. ITU-T H.621 (2008)/Amd.1 (10/2014) Figure II.6 Implementation architecture and workflow of the food safety check and purchase case The dual band RFID reader in the ID terminal can work sometimes as a UHF RFID reader, “ID tag R/W a)“, sometimes as an NFC reader and somet
46、imes as an NFC tag, “HF ID tag“. The “ID tag R/W b)“ and the “Payment Service System“ correspond to the conventional smart card payment service. II.6.3 Workflow 1) ID tag R/W a) in the smartphone reads the food identifier via UHF. 2) MIDF sends the food identifier to the IDR to find the food trace i
47、nformation server associated with food identifier. 3) IDR informs the location and transfer protocol of the food trace information server to the MIDF. 4) MIDF sends the location and transfer protocol information to the MIHF. 5) MIHF requests the food trace information server to obtain the food safet
48、y information. 6) The food trace information server replies with the food safety information. 7) The consumer reads the food safety information. 8) In case of buying the food, the consumer enables the payment feature of his/her smart phone and puts his/her smart phone, working as an HF ID tag herein
49、, to ID tag R/W b). 9) ID tag R/W b) sends payment information consisting of a credit card number, for example, to the payment service system. 10) The payment service system sends a payment operation result, i.e. success or failure, back to the ID tag R/W b) which, then, prints out a proper notice for receipt or failure. II.7 Visitor identification and guidance service with multimedia information II.7.1 Application scenario In this scenario, ID terminal is a kind of smartphone which has fo
